' My inventioncomprises certain improvements in web feeding mechanismwhereby webs'of heavy or light stock can be successfully fed byproviding the web feed rolls with removable web margin engaging ringswhich may be retained on the rolls when heavy material, such as;magazinestock, is to be fed and which may be removed when light or weakmaterial,'such as newspaper stock, is to be fed.

My invention further comprises a change speed drive for the said webfeed rolls, which drive includes a change gear mechanism for driving thefeed rolls at oneangular speed when the rings are retained and at agreater angular speed when the rings are removed, whereby the webwhether it be of heavy stock or of light stock may be fed at a predeten.

. mined speed by said rolls.

My invention more particularly comprises a gear train drive includingtwo coaxial driving gears of different diameters and a shiftableintermediate gear arranged to be brought into mesh with either one ofsaid driving gears. V

V A practical embodiment ofmy invention is represented in theaccompanying drawings, in which v Fig. 1 represents a diagrammatic endelevation, showing the web feed rolls with their web margin engagingrings retained, and the shiftable intermediate gear in mesh with thedriving gear for feeding the web of heavy stock; a

of the web feed rolls With the web margin engaging ringiremovedtherefrom Fig. 7 represents a side view of one of the web marginengaging rings. w I In the web feeding mechanism illustrated in theaccompanying drawings I have shown four webfeed rolls 1, 2, 3,4. 1 InFigs. 1', 2 and 4 the web feed rolls areprovid'ed with web marginengaging rings 5 "removably mounted thereon. These rings are shown assplit, for facilitating their mounting on and removal from the web feedrolls. The rings are also shown as having overlappin'gaends and as beingremovably secured on theweb feed roll by means of screws 6. "T hesejremovable web margin engaging rings 5 may HOWARD n1: BARBER, orPAwoA'ruoK, oo-nniio'rroutr, assls non ,TO, 0. B, corrTRE L a;

be of any predetermined thickness, to-cause the roll to properly feed aweb of heavy stock. In Fig. 1, I have shown aheavy web 7 as passingaround the web feed rolls in engagement with the removableweb marginengagin g rings on said rolls, while inFig. 3, I have shown a thin web 8as being passed around these web feed rolls with the Web marginengagingrings removed from said rolls.-

The drivefor the web feed rolls isherein shown as a gear train in whichtwo coaxial driving gears 9 and 10 are shown as mounted on a shaft 11which carries a gear '12 driven, in the'present instance, from a'p'inion13. An intermediate gear 14 is shiftable to two differentpositions' intwo planes, to bring it into* mesh with either the driving gear 9 by theweb feed rolls; In Fig. 1 the shiftable intermediate gearl is shown inone posi tion Where it meshes with the driving gear 9while in Fig. 3 itis shown inanother position where it meshes with the drivinggear 10. Inboth of these positions the shiftable intermediate gear' 14 mesheswithithe wide faced gear 15, which gear 15 is at alltimes connectedwit-h the web feed rolls through the train of gears 16, 17, 18, 19, 20and 21.'.

Fromthe above description it willbe seen that by simply shifting theposition "of the intermediate gear 14 to bring-it into engagement witheither the driving-gear 9 or the driving gear ofthe gear train, the webfeed rolls may be driven at a predetermined suro face speedwith orwithout their web margin engaging rings so that the web whether it be ofheavy material orlightmateria1 is driven at said predetermined speed,thereby permitting the feeding of webs of heavy or light stock in thesame web feeding mechanism.

It is evident that various changes may be resorted to in theconstruction, form and arrangement of the several parts withoutdeparting from the spirit and scope of my invention, and hence I do notintend to limit myself to the particular embodiment herein shown anddescribed, but
